Let's see A parent in 11th grade English at a Catholic school who berated me for giving his daughter a zero for her plagiarised paper. He demanded that she receive a C because she turned it in! A parent who couldn't understand how her daughter received an F when she had received a B on one quiz, but failed everything else, and didn't do about 60% of her work. She tried to prove to me with a calculator that if you add a B to an F it equals a B. The daughter had to intervene and tell her she deserved an F. The parent who asked for a conference because I was picking on her son. I had apparently written several referrals for his behavior (I had not, he actually was not a problem in my class), how I should not expect him to turn anything in because he had a child at home, and then whipped out her tape recorder to tape me without my permission. I told her she couldn't do that, and she started ranting about her civil rights, and threatened to have me arrested for interfering with her. When my P stepped in, she threatened to have him arrested. Best P I ever had, he said, "No, ma'am, you will be arrested if you continue to speak to my teachers that way. Now please leave my building before your son has to bail you out of jail." The parent who insisted that her child receive higher than a 30 on a research paper because he had worked so hard on it (it was riddled with grammar mistakes, etc.), that she demanded another teacher read it. Another teacher read it, told her that I was generous in my grading. She accused that teacher of colluding with me, and demanded my AP read it. He read it, agreed with both previous teachers, and then she accused him of protecting us. She demanded someone outside the building read it. He sent it to another school within the district who had no ties with any of us--the mother even selected them. That teacher also agreed with all of us, and sent us a copy of the email she sent the mother, "Be happy with the 30. I wouldn't let my dog crap on this." (I still keep this email). That child went on to squeak by and graduate (I got a thank you bouquet). I was secretly happy when one of his classmates came back the following year and told me that this child had enrolled at a local tech school and had dropped out within a week because Mom went to the school to berate his professors and he was so embarrassed and so incapable of doing the work that he left. A parent called a conference with my and my P a year after her child completed my class to ask that her F be changed to a D because I had graded the final too fast. I even had one tell me this morning that "I promised her I would put extra credit" on her child's grade for the 1st nine weeks (which I did, it is documented in our online software which can't be changed after the period ends), but says I didn't, she's been checking, and it's not there. And of course, she made sure to tell me that her son does not like me and that I'm too hard on him.
